    Hello, the programming pod was working, that is, I could program the EPCQ in Serial Mode and also over the JTAG. I have two headers on my board, one for programming the EPCQ and one header connected to the JTAG pins. Yesterday, I was connected to the JTAG port and had no problems programming the FPGA, but when I tried programming the EPCQ it gave an error message that no device was found. I asked my co-worker for his USB programmer and was able to program the EPCQ. We've seen this before and was able to fix the programming pod but I can't remember what device I need to replace on the programming pod.
